### This code will open one MainWindow and other Wait box, But WaitBox is not really on Top of MainWindow. I am trying to get a way by which this Widget can be placed on top of MainWindow and MainWindow should not get any user actions. This is usually seen in Windows Widgets, where parent window will not accept focus unless the Child window is closed.
Let me know if you have thoughts
